The invention relates to improvements in window constructions and hasfor its primary object the provision of an improved construction of thischaracter which is capable of economical manufacture and highlyefiicient in use.

Another object of the invention is the provision of an improved Windowconstruction having special provisions for enclosing and mounting thesash weights and connecting the same with the sashes whereby the widthand cost of the window frame is materially reduced.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understoo'd by reference to the accompanyingdrawings forming a part of this specification, and in which- Fig. 1 isan interior elevation of a window construction embodying the invention;

Fig. 2 an enlarged partial section taken substantially on line 2-2 ofFig. 1;

Fig. 3 an enlarged horizontal section taken substantially on line 33 ofFig. 1;

Fig. 4 an enlarged partial section taken substantially on line 44 ofFig. 2;

Fig. 5 a section taken substantially on line 55 of Fig. 4;

Fig. 6 a view taken substantially on line 66 of Fig. 4;

Fig. 7 a view taken substantially on line of Fig. 6; and

Fig. 8 an enlarged section taken substantially on line 88 of Fig. 4.

The embodiment of the invention illustrated in the drawings comprises awindow frame 10, preferably made of wood in the usual form except thatthe usual wells or spaces for accommodation of the sash weights are notincluded, but instead thereof special wells l are provided centrally ineach side thereof and a single sash weight I2 is arranged toreciprocate, as shown in each well Each sash weight 12 is suspended on apulley I3 connected therewith as indicated by a hook I4. The inner sideof each of the wells II is formed by a metallic strip formed in twolongitudinally registering parts l5 and I6, separated from each other ata medial plane l1 and removably secured in place by means of screws l8.The strip parts l5 and I6 are provided, respectively, withlongitudinally registering central beads l9 and 20 which constitute theparting strips for the upper and lower sashes 2| and 22.

The sashes 2| and 22 are otherwise mounted as shown in the usual way toreciprocate vertically in the frame III, as will be readily understood.

The angular bracket 23 is mounted as shown on frame l0 at the top ofeach of the wells II and apair of pulleys 24 is mounted as shown in eachbracket in angular relation with each other so that their outer sidesoverlie substantially the central portion of the corresponding well II.The inner sides of the pulleys 24 overlie rabbets or grooves 25 and 26in the corresponding sides of the sashes 2| and 22, as best shown inFig. 4, the upper strip parts |5 being notched as shown to permit ofthis arrangement. A flexible suspending element 21, which may be in theform of a chain, cord, cable, or the like, is arranged as indicated inFig. 5 with its central portion passing under the pulley l3 and its endspassing over the pulleys 24 and secured by hooks 28 to the correspondingsashes by means of screws 29,

and whereby a pivotal or swinging connection is effected with each ofsaid sashes.

By this arrangement a single weight l2 will sufiice for both sashes ateach side of the window frame; a compact, convenient and economicalconstruction is provided for the purpose; and ready accessibility isprovided to the upper portion of the weight wells and associated partsfor any necessary repairs or adjustments. The specific form andarrangement of parts constitutes a simple and effective construction andarrangement for the purpose.

While I have illustrated and described the preferred form ofconstruction for carrying the invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I therefore do not wish to be limited to the precise detailsdisclosed, but desire to avail myself of such variations andmodifications as fall within the scope of the appended claim.

I claim:

In a window construction, including a frame and a pair of sashesvertically slidable therein; a single weight wellin the frame at eachside thereof, said wells each comprising a vertical groove centrally ofthe sides of the frame, a substantially U-shaped strip member closingeach of said wells, said strip having a base and parallel side walls,said base and adjacent portions of said side walls extending inwardly ofthe sides of the frame, a weight in each weight well, a flexible memberconnecting each weight to each sash, a bracket carried by each frameside adjacent the top thereof and enclosed by the corresponding strip,openings through said parallel sides of said strips opposite saidbrackets, a pair of pulleys for each flexible member carried by eachbracket, and a portion of each pulley extending laterally through one ofsaid openings in the adjacent side wall of the enclosing strip.
